Ferrara
Alfonso I., Duke of Ferrara, himself occasionally worked in a room attached to his palace, and is said to have discovered a fine white colour, which was adopted by the fabriques of Urbino. He died in 1534. His successor, Duke Alfonso II., summoned Camillo Fontana (son of the celebrated Orazio Fontana of Urbino) in 1567 to give new life to the manufactory. All the well-known pieces bearing the impresa of the Duke, a flame of fire and the motto “ARDET ETERNUM,” were produced at this fabrique, about 1579. At a much later period, probably late in the 17th century, there was still a manufactory here.
